Fiance' charged twice during online payment

[JamieAndAmanda 0]

So my fiancé did the online interview appointment scheduling and she has been charged twice on her credit card once on 25 Oct for CA$305.47($265US) from CSC*US EMBASSY MRV and again on 29 OCT for CA$305.71($265US). How do we go about getting a refund for the extra charge ? She tried initially on the 25th and it said no interviews available even after she paid. then she logged in again on the 28th of Oct to see if interviews were available and she got one. Looks like it charged her twice though when she initially tried and again once she received an interview.

any help in dealing with double charges or a phone number/email to contact ?

I would contact my credit card company - the consulate is hard to reach (email works, just takes a while to get an answer).
